It sounds downright crazy, but Gym Jones manager Rob MacDonald proved that it's possible to blast 87 calories in one minute on an AirDyne Bike.
One reason this piece of equipment is so effective for torching calories?
Because it increases its resistance as you pedal harder.
The key to making the AirDyne Bike a powerful calorie-burning tool is to pedal at a high intensity, so it's a great way to perform HIIT workouts.
Note: This was by no means a scientific experiment, and it relies on the accuracy of the built-in AirDyne monitor, which calculates calories by converting revolutions of the fan into physical work.
